For good and cheap burgers, I can't think of a better place than Burger King - their flame broiled burgers just taste so much better than the rest of the fast food burger chains out there!
I am a regular customer of Mac D, Subway and KFC. Till date i think the food of Mac D, Subway and KFC are equally good and hygienic but I like KFC Meals a lot and visit the restaurant every weekends to enjoy Crispy Chicken with Coke...
